Inventors have found that in existing APK (Android Package, Android installation kit) executable file layout side
Formula are as follows: each virtual machine executable file in the APK, such as can include the source of multiple processes in classes.dex file
Code.It will lead in this way, when the process operation in multiple processes of the corresponding APP of the APK, need to load multiple virtual machines
Executable file into memory, and due in each virtual machine executable file for being loaded into memory in addition to the source comprising the process
Code is outer, also includes the source code of other processes, results in memory by the meaningless occupancy of the source code of other processes in this way.In particular,
When a part of process in multiple processes of the APP is all run, all virtual machines for almost needing to load in the APK are executable
File causes memory by excessive occupancy into memory, or even the case where low memory occurs.
In addition .class file during obtaining APK, is being converted to storage efficiency by dx order by the prior art
Higher virtual machine executable file: when classes.dex file, can not carry out remapping to the executable file in the APK,
Can not remapping be carried out to the source code in classes.dex file and classes.dex file, and then lead to memory quilt
Excessive the case where occupying, is unable to get solution.And in embodiments of the present invention, can in existing application program installation kit can
It executes file and carries out remapping.Specifically, which can be decompressed, obtains the executable text of virtual machine
Part.Then, it is based on preset configuration file, the corresponding source code of in the virtual machine executable file, each process is put into this

In addition, since multiple processes of APP1 may be corresponding with identical public source code.Therefore, in order to avoid every operation one
A process is loaded with primary public source code, causes memory by excessive occupancy, can determine the corresponding common source of multiple process
Code.Then, the corresponding common source of multiple processes is piled up into public source code virtual machine executable file.
Later, be based on preset configuration file, by virtual machine executable file classes1.dex, classes2.dex and
Source code in the corresponding source code of in classes3.dex, each process other than public source code, is put into the dedicated void of the process
In quasi- machine executable file.And by the dedicated virtual machine executable file of process obtain, each and the public source code virtual machine
Executable file is determined as remapping virtual machine executable file.Then, which is compiled
It translates and compresses, to obtain the APK1 " after executable file remapping, this is also rational.
In this way, only being needed when a process (such as process A) of the corresponding application APP 1 of the APK1 " runs for the first time
Load the dedicated virtual machine executable file and the public source code virtual machine executable file of process A.And when the APP1's
When another process (such as process B) is run, it is only necessary to load the dedicated virtual machine executable file of process B, reduce
To the occupancy of memory.
Wherein, in above-mentioned APK1 comprising virtual machine executable file classes1.dex, classes2.dex and
Classes3.dex and process A and process B are merely illustrative, are not limited thereto certainly.
